Title: Manufacture of sliding material
Inventor: KUROSAWA TAKASHI
IPC: F16C33/00
Filed: 1980-04-28
Abstract: PURPOSE: To enhance improvement of mechanical strength without reducing self- lubricating effect by a method wherein a metal or an alloy, etc. containing solid lubricant is cast in a hole made in a solid lubricant substrate and the substrate is cut so that the solid lubricant may be exposed.  
     CONSTITUTION: Graphite is used, for instance, as a solid lubricating substrate 4 and a hole with a desired depth or a through-taper hole is formed on said graphite substrate 4. The alloy which contains the solid lubricant, for example, molten bronze alloy 2 in which graphite powder 1 is dispersed at 10% by volume is cast into said taper hole 5 and cured. Then, the side of the open part of the taper hole 5 is machined along the A-A line. By this method, a sliding surface 7 is obtained where a metallic surface having dispersed graphite on the surface exists on the substrate 4. Thus, even though large holes are made to facilitate casting operation, dispersed graphite is exposed on the cast surface and desired sliding characteristics can be obtained as a finely oscillating and sliding material.

Title: Current collector for rotary electric machine
Inventor: KASAMAI HITOSHI
IPC: H02K13/00
Filed: 1986-03-17
Abstract: PURPOSE:To ensure stable operation without causing the difference in level and the rust to a collector ring even if the axial portions of the collector ring and a collecting brush are deviated, by slidingly getting into contact with the collector ring in arranging an insulated brush on the axially outside of the collecting brush. CONSTITUTION:In a current collector of a rotary electric machine, aside from a collecting brush 2 arranged corresponding to a collector ring 1, an electrically insulated brush holder 4 is provided, into which an insulated carbon brush 5 is inserted. This insulated carbon brush 5 will incur only a mechanical abrasion loss to the collector ring 1. By the sliding action of this brush 5 the sliding limits of the collector ring 1 keeping contact with the brush 5 is the same as it is ordinarily used. As the collector ring 1 moves in the axial direction and even if the contact positions of the collecting brush 2 and collector ring 1 may change, a good contact is still obtained, because the limits held as a sound sliding surface by the brush 5 will move accordingly. If the brush 5 comes into contact with a difference in level and with the rusted portion of the collector ring 1, no overheating, etc. will be caused as the current does not flow through it, so that stable operation can be performed.

Abstract: PURPOSE:To suppress the positional change of the center of gravity of a movable part to a small amount, to favorably balance the part, to miniaturize a magnetic field applying coil and to improve the rigidity by embedding the magnetic field applying coil in the outer peripheral part of a lens part. CONSTITUTION:An objective lens 2 is manufactured by molding and a cell part 2a and a magnetic field applying coil 14 are integrally composed by embedding the magnetic field applying coil 14 in the cell part 2a at the time of molding. A laser beam is converged by a lens part 2b, forms a light spot on the surface of an optical disk, a current is supplied to the magnetic field applying coil 14 through an electrode 15, the magnetic field is generated and information recording is performed by applying the magnetic field on the position of the light spot. In such a case, since the magnetic field applying coil 14 is comparatively miniaturized, the weight of a bobbin does not increase and the position of the center of gravity of the bobbin does not change largely. Further, since the magnetic field applying coil 14 is embedded in the cell part 2a, the rigidity is increased.

Filed: 1990-03-12
Abstract: PURPOSE:To obtain the above rare earth-iron magnet having high corrosion resistance by adjusting the atomic ratio of Co at 20% or more to the total amount of Fe and Co in all the metal phase except the main phase. CONSTITUTION:This magnet is a sinter of alloy consisting mainly of Fe and Co and containing R (indicating a kind or more of rare earth elements containing Y) and B and has all the metal phase except the main phase e.g. R-rich phase and B-rich phase contain Co and this metal phase contain the atomic ratio of Co at 20% or more to the total amount Fe or Co. Generally, Co is higher than Fe in corrosion resistance and therefore inhibits corrosion of metal phases by making a metal phase which starts corrosion contain a large amount of Co. This process can improve corrosion resistance of the whole magnet.

Abstract: PURPOSE:To easily produce the shadow mask, the inner shield and the mask frame of a color television picture tube with high yield by making the rolled surfaces of an Fe-Ni alloy containing face-centered cubic lattices consist of crystal faces (111) and using the alloy to form said parts. CONSTITUTION:An Fe-Ni alloy at least 70% of the crystalline particles of which consist of face-centered cubic lattices and the rolled surfaces of which consist of 30% of the crystal faces (111). The alloy is subjected to hot rolling once and cold rolling twice and then is annealed at a temperature above the recrystallization point to form a round mask. Each rolling of the alloy is performed with a rolling rate not exceeding 70% and the final rolling is performed with a rolling rate of at most 30%. The thus formed round mask is then treated in an oxidizing atmosphere to form a black film, thereby producing a shadow mask. A frame, an inner shield and a bimetal are also produced by similar processes except that etching or blackening is not performed. The proportion of face-centered cubic lattices to the crystalline particles of the Fe-Ni alloy is adjusted to at least 70% in order to facilitate equalizing the directions of the crystal particles. The rolled surfaces of the alloy are made to consist of crystal faces (111) in order to make the alloy suitable for accurate processing by reducing the spring back level.

Title: Formulation of insulating film and manufacture of semiconductor device by using it

IPC: H01L21/768
Filed: 1995-03-17
Abstract: PURPOSE: To make an insulating film excelling in flatness and humidity resistance by using tetraisocyanate silane as a source in forming the insulating film by vapor phase epitaxy. CONSTITUTION: A carrier gas of N2 gas or Ar gas is fed to raw materials vessels 11 and 12 containing water and for bubbling, and a generated gas is introduced to a reaction vessel 13 in which a semiconductor substrate 17 is arranged. The internal walls of the semiconductor substrate 17 and the reaction vessel 13 are temperature controlled by respective heaters 18 and 19. A comparison of the result of IR analysis immediately after film forming of a silicon oxide film to that of annealing it at 600 deg.C in vacuum shows that although a slight peak of SiOH is observed immediately after film-forming, annealing eliminates it substantially with a very little peak value. As a result, it is found out that the water content of the formed silicon oxide film is negligible with excellent humidity resistance.
